Simple Explanation

A special kind of computer network used to send sound and video with perfect timing.

Concise Technical Definition

AVB (Audio Video Bridging) is an IEEE 802.1 Ethernet-based standard that ensures synchronized, real-time transmission of audio and video data over network infrastructure.

Layman-Friendly Analogy

Like building a fast, multilane highway where sound and video signals can travel together without traffic jams or delays.

Industry Usage Summary

AVB is used in professional audio, conferencing systems, automotive infotainment, and AV installations to guarantee low-latency, synchronized digital audio/video over Ethernet. It enables reliable, plug-and-play network setups for audio systems without proprietary protocols.

Engineering Shortcut

AVB = IEEE 802.1 Ethernet standard for time-synced AV over LAN.

Full Technical Explanation

Audio Video Bridging (AVB) is a suite of IEEE 802.1 standards designed to deliver time-sensitive audio and video data over standard Ethernet networks. It includes mechanisms for traffic shaping, time synchronization (802.1AS), stream reservation (802.1Qat), and queuing (802.1Qav) to ensure low-latency, deterministic transport of media. AVB enables multiple AV devices—like speakers, mixers, and video systems—to connect and operate synchronously over a shared LAN, making it suitable for studio, live, and corporate installations requiring precise signal coordination.
